Descrição do produto
Fire Resistance Tester for Gypsum Board
Application

Designed to determine the fire stability of fire-resistant gypsum boards and assess the fire resistance of various building materials, decorative finishes, and interior decoration materials.

Test Procedure
  1. Drill holes in the test specimen and condition it under specified environmental conditions
  2. Suspend specimen between two flame nozzles using a support rod
  3. Position nozzles perpendicular to specimen surface, 30mm from board surface
  4. Use liquefied petroleum gas (LPG) as heat source
  5. Suspend load beneath specimen as per standard
  6. Measure temperature at 5mm from board surface using thermocouple
  7. Maintain temperature at (800±30)°C within 3 minutes
  8. Record time from fire exposure until fracture occurs
  9. Use minimum value among five specimens as fire stability rating
